An Empirical Study of the Microscopic Phases and Manufacturing Technology of a 14th-Century Blue-and-White Large Jar / 14世纪青花鱼藻纹大罐微观物相与制作工艺实证研究

This study takes a privately held 14th-century blue-and-white “fish-and-algae” large jar as its physical specimen and records microscopically the glaze layer on its surface, the high-temperature microscopic phase changes of its Sumaliqing cobalt pigment, and the trimming marks on its foot. Through macroscopic morphological comparison and microscopic mineral-phase analysis, it systematically sets out the physical and chemical causes of the phenomena observed, with the aim of providing a transparent, data-based empirical baseline for discussion of the craft of display porcelain from the 14th century Jingdezhen kilns. 本研究以一件私人收藏的14世纪青花鱼藻纹大罐为实物标本，显微记录了其器表釉层、苏麻离 青钴料的高温微观相变以及底足修胎工艺痕迹。通过宏观形貌比对与微观矿物相分析，系统阐述 了相关物理现象的化学成因，旨在为14世纪景德镇窑陈设瓷的工艺讨论提供透明、以数据为依 据的实证基准。
